Letters Patent No. 114,100, dated April 25, 1871.

IMPROVEMENT IN WAGON-BRAKES.

The Schedule` referred to in these Letters Patent and making part of the sanne.

I, SIMEON R. BOLTON, of Prescott. in the county of Pierce and State of Missouri, have invented a certain improved Automatic Wagon-Brake, of which the following is a specification.

v Nature and Object of the Invention.

My invention relates to a brake that is operated by the backward pressure of the neckeyoke against a lever pivoted to the fore end of the tongue, and to Whose lower end is attached a wire running beneath the tongue and fore axle and reach, and operating the brake and My invention consists mainly in the construction and arrangement of' the levers, the making 'of the front lever longitudinallyadjustable on the tongue and wire or rod, the manner of connecting the brakebar to the rear hounds, and the manner of connecting the friction-shoes to'the brake-bar.

.Description of the Drawing.

Figure 1 is a plan ot' the running-gear of a wagon to which my brake is applied.

Figure 2 is a longitudinal section of the same at the line x x, iig. 1.

Figure is an enlarged view, showing the connection of the brake-bar to the hounds.

Figure 4 is an enlarged view of the connection of the friction-shoes to the brake-bar.

General Description.

are the wheels; B and C, the fore and rear axle;` and b b c, the holsters. D and E are the fore and rear hounds. F is the reach or coupling-pole. ,G are the vcross-bars connecting the rearends of the fore hounds.

H is the tongue.

I is a lever in form of a iattened ring or link, whose sides are tule-ruined to the fore end of the tongue by a removable bolt, 1f, which passes through one of a series of transverse holes, 71., in the tongue.'

J is a ilat bar .of metal hinged to the lower end of the lever Land having a series of holes o'r eyes, j, to receive the hook 7c ot' the wire or roll K extending heneatli the tongue and 'ore axle to thelower end oi' the lever L, whose sides pass down each side of the reach and are pivoted thereto by a bolt, l, passing through the said sides and the reach. l

M is a spring attached to the rear axle, and whose end is connected hy a rod, m, to the lower end of the lever L.

The upper end of the lever Lis connected by rods n to the brake-bar N,\vhich latter is connected to the hounds D by a linkframe, O, so arranged that as the brake-bar is drawn backward it will be raised and carried up on top of the blockP, on which the bar rests when the brake is in action..

The brake-blocks or friction-shoes Q are connected to the bar by. links R R', a side view of Awhich is seen in iig. 4, so that they may be raised upward and thrown over from the wheel when the latter is turned .in a retrograde direction.

. tree.

The brake-bar N may be hung beneath the reach F. A

The operation of the brake is as follows When the wagon is running down hill the upper end of the lever I is pressed against the neck-yoke and driven backward, which draws the lower end forward and with it the rod K; this draws the lower end of the lever L forward, and its upper end with the brakebaris drawn backward, and the latter is thrown up onto the block P, and the friction-shoes Q are brought in contact with 'the rear wheels. When the wagon reaches .the bot-tom of the hill the pressure of the neck-yoke is removedfrom-the lever I and the spring M draws back the rod K, vand the lower ends of the levers L and I and the friction-shoes are removed from contact with the wheels.

v In backing the wagon the shoes are first brought in contact with the wheels as in braking; but as s oon as the wheelscommence to tui-n backward the shoes are thrown upward and away from the wheels, so as to be no impediment to the backing of the wagon.

C Za'ims.

I claim as my invention- 1. The combination ofthe brake-bar N, link or Alinks O, and rest-block P. substantially as and for the purposes set forth.

2. The combination and arrangement of the shoes Q, connecting-links B. R', and bar N constructed and adapted to operate as herein specified.
